Quo Vadis Venomics? A Roadmap to Neglected Venomous Invertebrates

Toxins, 2014
Venomics research is being revolutionized by the increased use of sensitive -omics techniques to identify venom toxins and their transcripts in both well studied and neglected venomous taxa.

Karyotype Variation and Environmental Adaptation in the Invasive Alien Freshwater Flatworm Girardia in China

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Our findings provide a comprehensive baseline of the distribution, reproductive strategies, and environmental adaptations of invasive Girardia species, and underscore the urgent need for continued monitoring and effective management to safeguard native biodiversity.

The dual role of detritus as resource and habitat: integrating non‐trophic processes to ecosystem dynamics

Oikos, Volume 2026, Issue 8, August 2026.
The diversity of ecological interactions, both trophic and non‐trophic, is central to understanding the assembly of communities. However, we have yet to study non‐trophic processes through their action on ecosystem compartments such as detritus involved in both recycling and habitat provisioning.

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, Volume 83, Issue 7, Page 496-514, July 2026.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Variation in Meiofaunal Abundance and Composition Across an Estuarine Bay: Do They Comprise a Coherent and Distinct Entity Displaying Contrasting Patterns to the Macrofauna?

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Is division of marine animals into macrofauna and meiofauna merely an arbitrary convenience, or, as has been claimed, does their size difference render them distinct and independent entities evolved under different ecological constraints? Those in the Knysna estuarine bay did not behave as distinct and discrete ecological entities, their individual ...

Changing Pacific Salmon Nursery Lake Ecosystem Dynamics Over Centuries to Millennia: Insights From Sedimentary DNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Sedimentary DNA metabarcoding tracks long‐term eukaryotic community change in Pacific salmon nursery lakes, revealing potential land‐use and climate influences on algal communities and resilience indicators. ABSTRACT Pacific salmon are keystone species in North Pacific freshwater, riparian, and marine ecosystems, but many populations have declined or ...

eDNA Collected by Custom‐Built Unmanned Surface Vehicles (USVs) Reveals Spatio‐Temporal Shifts in Tropical Coral Reef Faunal Communities

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Self‐constructed Unmanned Surface Vehicles were deployed at coral reefs on Reunion Island to capture environmental DNA (eDNA), identifying changes in animal communities depending on the time of day and sampling station. These findings suggest specific sites for high‐frequency, long‐term eDNA monitoring using low‐cost mobile devices.

Kicking in the guts: Schistosoma mansoni digestive tract proteins are potential candidates for vaccine development

Frontiers in Immunology, 2015
Schistosomiasis is a debilitating disease that represents a major health problem in at least 74 tropical and subtropical countries. Current disease control strategies consist mainly of chemotherapy which cannot prevent recurrent re-infection of people ...

Fossil constraints on the origin and evolution of Platyhelminthes are surprisingly concordant with modern molecular phylogenies [PDF]

Zoologia (Curitiba)
Trace fossils preserved with fossil worm-shaped remains suggest the presence of free-living flatworms during the Ordovician at the latest and their occurrence in terrestrial environments during the Permian.

Assessing the occurrence of alien species on Brazilian freshwater ecosystems: insights from a comprehensive survey [PDF]

Acta Limnologica Brasiliensia
: Aim Assessing the damage caused to natural environments and native biodiversity by alien species is challenging. We tested whether the number of detections of alien species is affected by total alien or total invader alien species richness ...
